    摘要: A tilt latch (10) for a sash window (12) has a bolt stop. The sash window (12) is disposed within opposed guide rails (16) on a master frame (14). The sash window (12) is comprised of a top sash rail (20), a base (22) and two stiles (24,26) connected together at their extremities. The tilt-latch (10) is adapted for releasably securing the sash window (12) to the master frame (14). The tilt-latch (10) is comprised of a housing (42) adapted to be supported by the top rail (20). The housing (42) has an outward end opening (44). A latch bolt (46) is disposed within the housing (42) and has a nose adapted for engaging a respective one of the guide rails (16). A protrusion (80) is located either on the latch bolt (46) or the housing (42) and a lock wall (86) is located either on the housing (42) or the latch bolt (46). The protrusion (80) has a stop surface (84) and is moveable between a first position defining a prevent position (94) wherein the stop surface (84) is adapted to abut the lock wall (86) to prevent retraction of the latch bolt (46) into the housing (42), and a second position defining a deflected position (96) wherein the stop surface (84) does not abut the lock wall (86) to allow retraction of the latch bolt (46) into the housing (42). The protrusion (80) is biased to the prevent position.

    摘要: A window stop (10) for limiting movement of a sliding window along a predetermined path of window movement is provided. The window stop (10) has a housing (12) having a cavity (20) wherein the housing (12) is adapted to be positioned adjacent the path of window movement. A bolt (14), operatively associated with the cavity (20), is moveable between a first position (BP1) within the housing (12) and thereby out of the path of window movement, and a second position (BP2) extending out of the housing (12) into the path of the window movement whereby the window is able to contact the bolt (14). An actuator (16) is pivotally supported by the bolt (14) between a first position (AP1) locking the bolt (14) within the housing (12) and a second position (AP2) allowing the bolt (14) to extend to its second position (BP2). A spring (58) biases the bolt toward its second position. The bolt (14) receives forces from the window contacting the extended bolt (14). A tongue and groove arrangement is provided to allow efficient distribution of forces from the bolt (14) to the housing (12).
